NOTE-SHEET.

Specification of Letters Patent.

Patented April '7', 1908.

Application filed May 6, 1907. Serial No. 372,265.

To all whom it may concern: 1

Be it known that I, PAUL RIESSNER, a subject of the German Emperor, residing at Wahren, near Leipzig, Saxony, German Empire, have invented. certain new and useful Improvements in Note-Sheets, of which the following is a specification.

My invention relates to improvements in the note-sheets employed for operating mechanical musical instruments and the like. Such tune-sheets have hithereto been made of paper or cardboard, which have the disadvantages that they are consequently subject to alteration according to the amount of moisture in the atmosphere, with the result that the playing levers or other devices used, vary in their operation and thus do not always operate correctly. To overcome this defect I employ ordinary soft oilcloth in the manufacture of the note-sheets.

The oil-cloth is cut up into strips of the de sired width, just as is done at present in the case of other material, and is perforated to accord with a pattern. The strength of the sheet of oil-cloth is not appreciably weakened by being perforated and since it does not suffer under the influence of moisture, it will not become distorted, not stretch nor shrink. This cloth is also particularly adapted. to receive all descriptions of impressions or characters relating to the piece of music, thus, for example, the marks denoting the expression, how the piece is to be played, whether more or less intonation is desired, and the like.

noises.

With the paper or like note sheet heretofore used, the playing levers, in sliding contact with the surface of the sheets, cause quite a loud, foreign noise, spoiling to some extent the musical effects, said noise being louder with sti'lfer sheets. Owing to the soft surface of the oil-cloth, this foreign noise is almost wholly avoided.

Of greater value for the purposes of this invention-is the softness of the cloth because, the dropping of the levers at the edges of the slots is gradual and almost noiseless, the abrupt dropping of the levers off the edge of the slots of the stiff paper or board now used, and the scraping of the levers on side edges, causing the greater part of such foreign The bending down of the soft edges of the slots in my improved sheets of oil cloth under the action of the levers, permits of the gradual, easy, noiseless sliding oil of the levers.

Having thus described my invention, what I claim as new is Anote-sheet for mechanical musicalinstruments and the like, made of oil cloth, substantially as and for the purposes set forth.

In testimony whereof I afliX my signature in presence of two Witnesses.

PAUL RIESSNER.
